My chemist hubby was in the room and he said (I'm paraphrasing from memory)
carbon would take out most organics and most medicines are organic. That's
why we have to take the carbon out of our aquariums when adding certain
treatments, antibiotics, formalin, etc.

RO, otoh, takes out those plus heavy metals and basically gives you what
amounts to DeIonized water.

So it is probably wise for everyone to have some sort of carbon filtration
on their drinking water source. We use a separate under-the-counter unit
that serves both our frig and a small tap at the sink, so washing water
doesn't waste the unit's usefulness. ~ jan


I wonder if these small carbon water filters take such stuff out or reverse
osmosis filtration? ~ jan

Well, my sister has the uber-paranoid water treatment unit for her
drinking water. It's a filter that has its own little "house" on the side
of her house that does RO, charcoal and something else (can't remember,
just she always says 3-stage filtration). But even that I don't know if it
would handle all these pharmacutical pollutants.

See my ponds thru the seasons and/or my filter design:
